CHARLES C. BOWMAN, OF PITTSTON, PENNSYLVANIA.

GRATE FOR S'l'OVES.

SPECIFICATION forming part of Letters Patent No. 351,896, dated November 2, 1836.

' Application filed April 28, 1884. Serial No. 129:531. (No model.)

To all whom it may concern: Be it known that I, QHARLEs G. BOWMAN, of Pittston, in the county of Luzerne and State of Pennsylvania, have invented an Improvement in Grates for Stoves, of which the fol-.

- can be dumped when the fire is to be made afresh, or even while the fire is burning, by moving the central grate. I also provide a fire-pot in the form of or having below it a hanging or basket fire-pot, and rotate the same by gearing, so as to free the fuel from ashes and shake the same down, or to cause the fuel to descend from a magazine above the fire-pot. The space between the basket and the revolving grate or ring allows for the removal of clinkers. i In the drawings, Figl re l is a vertical section of the improvement.. Fig. 2 isa plan, partially in section, of the fire-pot and grates; and Fig. 3 shows the supporting-ring separately. y

The case A of the stove is of any desired character, and it may have openings and doors, or windows, as desired. There are supports 1) for the axis 0 of the circular grate d. This axis 0 passes through the case A, and it may be moved by a key or shaker, so as to agitate the fuel, or to dump the contents of the stove, orto remove clinkers.

The ring e is supported by arms e, that rest in sockets'or recesses in the inclined flange e, and upon this ring e rests the revolving gratering f, which is preferably in theform of a flat ring with grate-bar surface;v but it may be 4 5 plain or corrugated, or formed with the radial bars extending from the ring 3 to the ring 2. There are guide-fingers 4 passingfrom the grate f down inside the ring 2, and hooking beneath the bottom of such ring, so that the 5o revolving grate can be turned around wholly or partially, and with any desired rapidity, by the action of the pinion h and the circular rack of teeth at t on the under side of the ring 2. The fingers 4 steady the ring f, and prevent the same tipping sidewise, and the ring-support e is notched, as shown in Fig. 3,

to allow the hooked ends of the fingers 4 to pass down below the lower edgeof this ring e asthe ring f is-put into its place. The axisof the pinion hpasses through a tubular bearing, is, in the case A, and terminates with a square for the reception of a crank or other device, by means .of which the pinion may be revolved.

Above the ring or grate f there is a fire-pot. I have shown the same as formed of the ring m, with depending bars at, that are preferably slightly inclined, as shown." The lower ends of these bars n may be tied together by a ring cast with them, if desired, as shown by dotted lines at at". These bars form an open fire-pot or the lowerpart of the firepot.

Upon the under side of the ring m there are teeth 6, and the ring and fire-pot are supported by the flanges s, that project inwardly from the case A; or'the ring m may be suspended below the stationary portion of the fire-pot in any'desired manner.

The fire-pot can be revolved by the pinion 1, the teeth of which gear with the teeth 6, and the axis of the pinion passesthrough a tubular bearing, t, in the case A, and the outer end of such axis is square, so as to be turned by a crank. If desired, this fire-pot and grate may be below the magazine a, in a self-feeding stove.

It is now to be understood that the fuel may be shaken down and the ashes discharged by rotating or partially rotating the open fire-pot or fire-pot section, or the circular ring f,- or the fuelor ashes or clinkers may be dumped by the grate (I, thus giving great facility for controlling the combustion of the fuel. Olinkers may also be removed or escape between the lower ends of the bars n of the fire-pot and the ring f, and escape over the edge of such ring-grate and fall into the ash-pit. The grate d is adapted to dump the clinkers or the fire,

and such dump-grate is preferably made to outside of the hanging fire-pot to support the 3.
